Coherent CW is a method ofsending and receiving Morse code with
equipment which allows the window length, pulse phase,
and frequency of the signal to be accurately know and used
by the receiving equipment.



The result is a receiver with a bandwidth of only a few cycles
for CCW and something over 20 dB improvement in signal to
noise ratio in compairson to ordinary CW communication.

communciation among those interested in this technique.
